Title: Induction heater for seam welded pipe
Inventor: SAKIMOTO YUKIO
IPC: C21D9/08
Filed: 1986-10-28
Abstract: PURPOSE:To permit maintenance of the specified gap between a heating inductor and part to be heated by providing a mechanism to move and adjust the position of the inductor in accordance with the detected value of the fluctuation in the position of the part to be heated to a device for subjecting a weld zone to a heat treatment during the manufacturing process of a seam welded pipe. CONSTITUTION:The weld zone of the traveling seam welded pipe 1 is continuously heat-treated by the induction heating with the inductor 5 provided in correspondence thereto. A guide roll 8 revolves and a voltage is thereby generated in a tachodynamometer 18 when the pipe 1 is curved to the inductor 5 side by the effect of the induction heating and is transported under the contact with; for example, the roll 8 during this operation. The control part of the device drives a motor 14 to raise the inductor 5 and the roll 8 simultaneously. The motor 14 stops when the roll 8 detaches from the pipe 1. The above- mentioned curving of the pipe 1 maintains the stationary state during the heating when said curving attains the prescribed value and, therefore, the movement is so controlled as to raise the inductor 5 while the position of the pipe 1 is detected by utilizing the meter 18 until the stationary state is attained. The gap G between the weld zone and the inductor 5 is thereby maintained constant.

Title: Apparatus for supplying controlled medium pressure co2 in simple and convenient disposable container
Inventor: JIYOOJI PURESUTAA
IPC: B67D1/04
Filed: 1988-10-14
Abstract: A gas generator chemically generates a gas from a chemical reaction between two reagents (Ra,RB) contained within a common container. The reagents are normally separated by a gas generation chamber (Gb) into different regions of the container in the absence of gas generation therein. A reference pressure source (GA) of a predetermined pressure forces the two reagents into contact with each other when the pressure of gas in the gas generation chamber is less than the predetermined pressure. A valve (V) in fluid communication with the gas generation chamber (GB) is provided to withdraw the generated gas from the chamber when OPEN. As the gas flows through the valve from the chamber the gas pressure in the chamber drops permitting more mixing of the reagents. When the chamber pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source, the reagents become separated again and gas generation ceases.
